yes, do tell.....I was always itching to do a pulley mod as well....I herd the difference is the same as when you have the A/C running and turn it off???

I would tell you bout the difference but I couldn't notice much on my 320 motor. I have the UUC underdrive pullies also. I just noticed a minor ease on getting to higher rpms. I'm sure I'll actually feel them on this years new engine when they get switched over.

ya there is a slight difference especially in first gear... RPM's are smoother power steering is tighter (which a prefer with my lowering)... I just cant wait to do my fan delete next month to c how that will be with the pulley combo

I've done the fan delete also... It's hard to notice many gains on a 320 motor. This is why I asked how you like the gains on your 325. I was wondering if they were any different.
